why does your hair change after chemotherapy. hair is a genetic code in your DNA so does that mean that it changes your DNA?
Hair has a very high metabolic rate just like the cancers you are treating with chemotherapy. These chemotherapeutic agents get to cells that have a high metabolic rate, which include: hair, elements of bone marrow, intestinal cells. So when you get chemotherapy, it gets to all of the fast growing cells. That is why people become anemic on chemotherapy, or get diarrhea from damage to the intestinal lining of the stomach and intestines, so I would expect that if the hair is not forced into its telogen cycle, the hair growing out would not be normal.
